CyberSwaraj: Nostr, Cryptography Basics & How It Actually Works
A beginner-to-intermediate friendly workshop for anyone curious about real digital privacy.
Tired of platforms that own your data, shadow-ban your voice, or can disappear overnight? This hands-on session pulls back the curtain on Nostr — a simple, open protocol for decentralized social networking — and the cryptography that makes it possible. No prior technical background required; just curiosity.
What You'll Learn
Part 1 — Cryptography Basics (Demystified)
Why privacy isn't "having something to hide" — it's about control
Public vs. private keys: the foundation of digital identity
Hashing, signatures, and encryption — what they do and when to use each
How you already use this technology everyday without realizing it
Common myths about anonymity and what actually protects you
Part 2 — What Is Nostr?
The problem Nostr solves: platform lock-in, censorship, and identity fragility
How Nostr works: events, relays, keys, and clients
Your keys = your identity. Your data = portable across apps
Practical setup: create your first identity and post your first note
Part 3 — Nostr Technicals (Made Approachable)
Event structure and kinds — the grammar of the protocol
Relays: what they are, how to choose them, and why many is better than one
NIPs (Nostr Implementation Possibilities) — the standards that keep the network compatible
Zap (Lightning payments) basics and why they matter for creators
Security habits: key storage, signing devices, and avoiding common pitfalls
Who This Is For
Beginners curious about privacy and decentralized tech
Builders, writers, and creators wanting platform independence
Intermediates who've "heard of Nostr" but never really understood it
Anyone who's lost an account, been shadow-banned, or worries about data ownership
What You'll Walk Away With
A working Nostr identity and your first published note
A clear mental model of cryptography fundamentals
The confidence to evaluate privacy tools critically
Resources and a community to continue learning
Format
Interactive mini-lecture + live demos + guided setup time + Q&A. Bring a laptop or phone. No coding required to participate; code examples available for the curious.
Privacy isn't a feature you buy — it's a skill you build. Come learn it with us.
Privacy is not about hiding.
Most conversations about privacy start by making you feel paranoid. This one won't.
Privacy is something ordinary and human. It's the ability to decide what parts of your life get shared, when they get shared, and with whom. In the physical world this feels obvious. You close the door when you change clothes. You lower your voice in a crowded room. You don't hand your diary to a stranger.
Online, we've slowly given up all of that, usually without realising we were giving anything up. Each app asks for a small permission. Each service collects a small piece of information. Individually, none of it feels like much. Put together, it forms a surprisingly complete picture of how you live, think, move, and talk to people you love.
What is the 'CyberSwaraj' event series about
CyberSwaraj is a gathering for anyone interested in digital privacy, open-source tools, and taking back some control over their digital life. We run sessions for beginners, workshops for people ready to go deeper, and occasional deep-dives for the technically curious. Developers, privacy advocates, and people who've simply had enough of being tracked are all welcome.
